Biology 2011-12

Semester 2

Biology 1/30/12Week of 1/30 to 2/3

• ANNOUNCEMENT: Each entry task will be worth 2 POINTS this semester. Total of 10 points in a typical week.

• ASSIGN TABLE LEADERS. 2 Extra Credit points/week EVERYONE AT TABLE has the sheet complete and turned in.

• Entry Task – Monday• If you needed to explain photosynthesis to a 3rd

grader, what would you say? Please write it out for your entry task

• Take out photosynthesis labs and review answers.

Biology 1/31/12

• Entry Task – Tuesday

• On a scale of 1 to 4, how well do you think you met these standards?

• I can explain how plant cells use photosynthesis to produce their own food. Use the following equation to illustrate how plants rearrange atoms during photosynthesis:6CO2+6H2O+light energy —> C6H12O6+6O2

• I can explain the importance of photosynthesis for both plants and animals, including humans.

• Please also enter your self-assessment on your red sheets.

Act out Photosynthesis• Lab station – plant cell with chloroplasts• One actor as the Sun• Six actors as 6 carbon dioxide molecules (each containing 1 carbon

and 2 oxygen atoms)• Six actors as 6 water molecules (each containing 2 hydrogen and 1

oxygen atom)• One person ready to become 1 glucose molecule (containing 6

carbons, 12 hydrogens, 6 oxygen atoms)• Six people ready to become 6 oxygen gas molecules (each will contain

2 oxygen atoms).• AFTER ACTING – sit down and write a reflection – 10 minutes. What

happens during photosynthesis? What molecules start the process? What do they change into? What are the products of the process?

• If you understand photosynthesis better now, update your red sheets.

Biology 2/1/12

• Entry Task – Wednesday

• Read page 228 in the Biology textbook. Please define cellular respiration IN YOUR OWN WORDS.

• Get labs out and begin.

Introduce Cellular Respiration• STANDARDS (EALR 4 LS1 ):• I can explain how the process of cellular respiration is

similar to the burning of fossil fuels (e.g., both processes involve combustion of carbon-containing compounds to transform chemical energy to a different form of energy).

• I can describe the role that enzymes play in the breakdown of food molecules and synthesis of the many different molecules needed for cell structure and function.

• I can explain how cells extract and store energy from food molecules.

• Conduct lab – quickly, efficiently, carefully. Follow instructions, please

Biology 2/7/12

• Entry Task – Tuesday

• Consider your group’s data table. How does the concentration of sugar affect cellular respiration in yeast? In which flask (high or low sugar) was more CO2 produced?

• Lab due WEDNESDAY. We will share data and work on questions together TOMORROW!!

• TWO Important assignments today to practice for HSPE.

Biology 2/8/12

• Entry Task – Wednesday

• Listen as Ms. Maring reads article about cajun crayfish. • Write a summarizing sentence using: • IDENTIFY (who what where) - VERB – FINISH SENTENCE. • Thank you table leaders for all your hard work helping your

team!!!• Today we will complete an article summary as practice for HSPE. • We will also learn how our answers are scored and score a

person’s answers near us. • PS If you did not finish the text feature assignment from

yesterday, please do so today (Cheyenne, Braiden, Tim, TJ, Ryon, Jeremy, Dylan, anyone else???)

Practice for HSPE – Reading 10th grade

• Text and Text Features• Summarizing• Scoring using a rubric• Each answer can only get a MAXIMUM of 2

points…but include extra as a safety measure.

Biology 2/9/12

• Entry Task – Thursday

• In which kinds of cells does cellular respiration occur? • In which organelles?

• Complete article summaries.• Grade another person’s summary using the rubric. • EXTRA TIME? Please take out lab…make sure you have

complete data from someone (Example – Briana, Tim, Skyler, Justin, Justine, others???). Begin answering questions…

Biology 2/10/12

• Share answers to lab and turn in cellular respiration labs.

Act out Cellular Respiration• ENZYMES

• C6H12O6 + 6O2 6CO2 + 6H2O and ATP• The hallway is the lungs. • 6 oxygen molecules will enter and be carried by the BLOOD to the

cell. • Inside the mitochondria, the glucose molecule will be “burned”

with the oxygen. • ENZYMES help. • Rearranging into carbon dioxide, water, and ATP.• 6CO2 is carried away by the blood, to the lungs, to be exhaled. • DURING cellular respiration, the CHEMICAL ENERGY in glucose, is

transformed into the energy molecule ATP.• ATP will be used to do the work of the cell, like building DNA,

proteins, lipids, transporting vesicles, etc.
